The equation that shows how the total number of cups of ice used, y, depends on the number of glasses filled, x, is 
<h3>
Linear function</h3>
Filling the cooler is an illustration of a linear function
A linear function is represented as: 
Where
- m represents the slope/rate
- b represents the y-intercept/the initial value
- x and y are the variables
<h3>The equations</h3>
By comparison, we have the following parameters
--- the amount of cups per ice
---- the initial amount of cup
So, the equation that represents this scenario is

Answer:
4. y = 8 - x is the right answer
Answer:
QR=2x=16
Step-by-step explanation:
2x+8= 3x
8=3x-2x
8=x
QR=2x= 8*2=16
Answer:
8. The coordinates (0,0) represent the fact that when 0 minutes has passed, the horses have gone 0 miles because they hadn't started yet.
9. From the graph, it looks like horse A takes 4 minutes and horse B takes 2.5 minutes (aka 2 minutes and 30 seconds) to travel 1 mile.
10. For A: y = (1/4)x
For B: y = (2/5)x
11. For A: 3 miles
For B: (24/5) miles, or 4 and (4/5) miles.
12. Can't see the entire problem sorry.
Step-by-step explanation:
9. You find this by going to y=1 and look towards the right till you find the point the line intersects with y=1. Then find the x value by finding the corresponding number on the x axis.
10. A linear function will look something like this: y = mx+b, where y is the y value, x is the x value, m is the slope, and b is the y-intercept. Since both lines start from 0, you don't have to write the y-intercept since there's no point in writing +0. To find slope, you find delta y over delta x. Basically just find the difference of two y values and the difference of two x values from the same coordinate in the same order. I know that sounds really confusing but your teacher will probably teach this later on.
11. x represents the time, so just substitute x as 12 in the equation.
Answer:
8x²+5x+1
Step-by-step explanation:
3x²-5x+12
5x²+ x - 11
________
3x²+5x²= 8x²
}
5x+x =5x
}
12-11 =1
=
8x²+5x+1
